Some questions for any users of the Sony RX100 III: How useful do you find the EVF? Are there any issues with it in bright sunlight as there can be with EVFs on some other cameras? Have you used the RX100 III's digital zoom? Does image quality hold up if you don't get carried away? For context, I am also looking at the Canon G7X, which offers optical zoom out to 100mm. If I were to use digital zoom on the Sony out to 100mm - or even 200mm, what kind of results can I expect? I've tried this on other cameras and the results can vary widely, to say the least.
